Abstract Scope |
Powder-based direct energy deposition (p-DED) process has been pursued in repairing and enhancing the surface properties of large components, e.g. beams and rings operating at high temperatures and corrosive environments in industrial furnaces, with creep and wear identified as the primary failure modes. This work aims to showcase the integration of multi-scale and multi-physics computational methods, i.e., Integrated Computational Materials Engineering (ICME), in addressing the key process-structure and structure-property relationships in the laser-cladded Haynes 230 alloy. The developed ICME framework allows for accelerated design and refinement of alloy composition (including impurity levels) and the associated processing parameters for improved combination of deposited materials properties and process efficiency, while reducing the need for costly and time-consuming experimental trials. Interaction between the steel substrate and the cladding is also discussed. |
